Maleic Acid

Maleic acid (also called cis-butenedioic acid), a white crystals easily soluble in water, acetone, and alcohol, is an unsaturated organic dibasic acid which carboxylic acid groups are next to each other in the cis form. Its trans form isomer is fumaric acid, both are used in making polyesters, alkyd resins, plasticizers and lubricating oils. Maleic anhydride is the main source of maleic acid produced by the hydration. Maleic anhydride is prepared commercially by the oxidation of benzene or by the reaction of C4 (butane) with oxygen in the presence of vanadium catalyst. The physical properties of maleic acid and fumaric acid are very different each other. The cis isomer is the less stable. Maleic acid is used in the preparation of fumaric acid by catalytic isomerization. and other chemical products as a carboxylating agent. It is used as an oil and fat preservative and food acidulant.
